Background and Purpose: Genetic diversity is the basis for adaptation and survival of tree species under changing environmental conditions, representing the key issue of stability and productivity of forest ecosystems. This paper studies the marginal population characteristics and stand dynamics of aspen tree (Populus tremula L.) in natural, pure and mixed forest stands with Scots pine (Pinus sylvestris L.). These populations were observed on founding sites between Timarli Valley and Timan Plateau located in Pasinler in the Erzurum Province in Turkey.
Materials and Methods: Three replicated sample sites were established according to a randomised block design …

Six Key Components Of A Farm Or Ranch Business Plan, Jay Parsons

Cornhusker Economics

Developing a good farm or ranch business plan can have many benefits. In an earlier Cornhusker Economics article, I outlined six good reasons to develop a business plan (Parsons 2015). It helps to get your business organized and moving in the right direction. It lets your lender know you have a plan to succeed, which opens up your access to capital. It also helps you organize your thoughts, clarifying the goals and objectives you wish to achieve. In summary, putting together a written business plan increases the likelihood of your business achieving success (Scarborough 2011).

Dependence Of Aspen Stands On A Subsurface Water Subsidy: Implications For Climate Change Impacts, D. M. Love, M. D. Venturas, J. S. Sperry, P. D. Brooks, J. L. Pettit, Y. Wang, W. R. L. Anderegg, X. Tai, D. S. Mackay

Aspen Bibliography

The reliance of 10 Utah (USA) aspen forests on direct infiltration of growing season rain versus an additional subsurface water subsidy was determined from a trait- and process-based model of stomatal control. The model simulated the relationship between water supply to the root zone versus canopy transpiration and assimilation over a growing season. Canopy flux thresholds were identified that distinguished nonstressed, stressed, and dying stands. We found growing season rain and local soil moisture were insufficient for the survival of 5 of 10 stands. Six stands required a substantial subsidy (31–80% of potential seasonal transpiration) to avoid water stress and …

Jerome Powell Is Not The Bad Guy, Tim L. Meyer

Cornhusker Economics

One of the maxims often heard in economics, agriculture, and politics is that those who do not learn from history are bound to repeat it. At first glance, this is a pessimistic view of human behavior. However, I believe that in some part it is a reflection of the positive spirit exhibited by many Americans. While it is true some have not bothered to learn from history, others have simply emphasized the positive times while simultaneously limiting the memory of more challenging experiences.

Phylogeographic Analyses Of A Widely Distributed Populus Davidiana: Further Evidence For The Existence Of Glacial Refugia Of Cool‐Temperate Deciduous Trees In Northern East Asia, Zhe Hou, Zhaoshan Wang, Zhanyang Ye, Shuhui Du, Shuya Liu, Jianguo Zhang

Aspen Bibliography

Despite several phylogeographic studies had provided evidence to support the existence of glacial refugia of cool‐temperate deciduous trees in northeast China, the species used in these studies were limited by the species ranges, which could not exclude the possibility that northern populations were the colonists from southern refugial populations during the last glacial maximum (LGM). Here, we estimated the nucleotide variation in Populus davidiana, a widespread species distributed in Eurasia. Three groups in northeast, central, and southwest China were constructed according to the simulation results from SAMOVA, composition of chloroplast haplotypes and structure results. We revealed that the northeast …

Societal Rebirth: The Importance Of Spirituality, Lauren Rothstein

English Department: Traveling American Modernism (ENG 366, Fall 2018)

This article offers an exploration of what the social consequences are when modernity strips away religious-human relationships to the land. The two texts Black Elk Speaks and Grapes of Wrath both include moments of anonymous forces imposing systematic modernization on society. Particularly, I try to understand the controversial subject of societal rebirths, traditionally defined through employment and steady food source availability. This paper proposes an approach to societal rebirths that emphasizes the importance of spiritual connection to the land through a critical analysis of Bakhtin's theory of Chronotope and Leopold's theory of Land Ethic. On the issue of spiritual connection …

Recoupling Fire And Grazing Reduces Wildland Fuel Loads On Rangelands, Heath D. Starns, Samuel D. Fuhlendore, R. Dwayne Elmore, Dirac L. Twidwell Jr, Eric T. Thacker, Torre J. Hovick, Barney Luttbeg

Department of Agronomy and Horticulture: Faculty Publications

Fire suppression and exclusion, the historically dominant paradigm of fire management, has resulted in major modifications of fire-dependent ecosystems worldwide. These changes are partially credited with a recent increase in wildfire number and extent, as well as more extreme fire behavior. Fire and herbivory historically interacted, and research has shown that the interaction creates a unique mosaic of vegetation heterogeneity that each disturbance alone does not create. Because fire and grazing have largely been decoupled in modern times, the degree to which the interaction affects fuels and fire regimes has not yet been quantified. We evaluated effects of fire-only and …

Impact Of Ethanol Process Changes On Distillers Grains For Beef Cattle, Shelby Garland

Department of Animal Science: Dissertations, Theses, and Student Research

Distillers grains plus solubles (DGS) have been widely utilized in beef cattle diets. Fractionation of the corn kernel pre- and post-fermentation has changed the composition of DGS and allowed for the production of other feed byproducts over time. The use of fractionated DGS and other feed byproducts from the ethanol industry has not been heavily researched in beef cattle diets. Three experiments were conducted to evaluate the effect of feeding high protein distillers grains (HiPro DDG) and corn bran plus solubles (Bran + Solubles) in beef cattle diets. Experiment 1 evaluated the effect of byproduct type on finishing performance and …

Deep Soils Modify Environmental Consequences Of Increased Nitrogen Fertilizer Use In Intensifying Amazon Agriculture, Kathi Jo Jankowski, Christopher Neill, Eric A. Davidson, Marcia N.

Agricultural intensification offers potential to grow more food while reducing the conversion of native ecosystems to croplands. However, intensification also risks environmental degradation through emissions of the greenhouse gas nitrous oxide (N2O) and nitrate leaching to ground and surface waters. Intensively-managed croplands and nitrogen (N) fertilizer use are expanding rapidly in tropical regions. We quantified fertilizer responses of maize yield, N2O emissions, and N leaching in an Amazon soybean-maize double-cropping system on deep, highly-weathered soils in Mato Grosso, Brazil. Application of N fertilizer above 80 kg N ha−1 yr−1 increased maize yield and N2O emissions only slightly. Unlike experiences in …

Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain our ability to expand the cultivation of crops into environments that differ from those under which domestication occurred. We address this need in chickpea, an important pulse legume, by harnessing the diversity of wild crop relatives. We document an extreme domestication-related genetic bottleneck and decipher the genetic history of wild populations. We provide evidence of ancestral adaptations for seed coat color crypsis, estimate the impact of …

Similarity Of Introduced Plant Species To Native Ones Facilitates Naturalization, But Differences Enhance Invasion Success, Jan Divíšek, Milan Chytrý, Brian Beckage, Nicholas J. Gotelli, Zdeňka Lososová, Petr Pyšek, David M. Richardson, Jane Molofsky

College of Agriculture and Life Sciences Faculty Publications

The search for traits associated with plant invasiveness has yielded contradictory results, in part because most previous studies have failed to recognize that different traits are important at different stages along the introduction–naturalization–invasion continuum. Here we show that across six different habitat types in temperate Central Europe, naturalized non-invasive species are functionally similar to native species occurring in the same habitat type, but invasive species are different as they occupy the edge of the plant functional trait space represented in each habitat. This pattern was driven mainly by the greater average height of invasive species. These results suggest that the …

Soil Health Effects And Stakeholder Perceptions Of Manure And Woody Biomass Application To Cropland In Nebraska, Linda R. Schott

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Organic products that have historically been viewed as waste products may improve soil health by adding carbon (C) and nutrients to soil. Two such products are woodchips, generated from forest or rangeland management activities, and livestock manure. In Nebraska, eastern redcedar (Juniperus virginiana L.) is a native but invasive tree species inhibiting rangeland productivity. Livestock manure that is underutilized while inorganic fertilizers are imported for crop production presents a water quality risk by contributing to local- and regional-scale nutrient imbalances. Increasing the responsible use of livestock manure in crop fertility programs to improve sustainability of both livestock and crop farms …

Red Mite On Blackberry [Acalitus Essigi (Hassan)], Michael Caron, Sheriden M. Hansen, Taun Beddes, Ryan Davis, Ann Mull, Diane G. Alston, Claudia Nischwitz

All Current Publications

Redberry mite is a microscopic pest of blackberry that causes drupelets (small fruit sections) to remain hard and red (or less commonly hard and green) on an otherwise normally-ripened blackberry. The red drupelets can occur from a single drupelet to the entire berry. Redberry mite largely affects late-maturing blackberry varieties. Once it is detected, control is ineffective for that season's crop; control can be obtained in subsequent seasons by a variety of management practices. It was first reported in Utah in 2017 in Davis County
